Bill, Apologies for the delay, but I don't think any of the core NUT developers have serial-based APC units anymore. Is this a built-in serial port, or is it a USB-to-Serial adapter? If it's the latter, can you provide information on the hardware and the driver in use?
I don't think we have a way to adjust the debug level of a driver once it has started, but you might be able to get a bit more info with "strace -p <pid-of-driver> -o logfile" (which should attach strace to the running process until you hit Ctrl-C). -- - Charles Lepple On Sun, Jul 12, 2009 at 12:15 PM, Bill Arlofski<[email protected]> wrote: > > Ping...
